Winston Churchill's said, "Never give in, never give in, never, never, never, never, in nothing, great or small, large or petty, never give in except to convictions of honor and good sense." This encourages me to fight, especially for kids in classrooms. They deserve better.

6000 Skulls

I just spent the day trying to really get my head around human evolution at the Hall of Human Origins in the National Museum of Natural History. I think I'm getting it. Australopithecus died out. Homo heidelbergensis is probably the common ancestor of modern humans and Neanderthals. Homo erectus lived a long time and was pretty dang tall.

The biggest thing I'm pondering as I walk away is how all that we know about early humans is based on 6,000 skulls. That seems like a low number. On the one hand, the number doesn't bother me. 6,000 is a pretty hefty count for any collection of specimens. Even just 1 piece of evidence is something that science must deal with, as long as it is authentic. And 6,000 is a lot more than 60 or even 600.

On the other hand, that seems like such a small number to answer the question, "Where did we come from?" In my day-to-day world, people don't believe in human evolution. I don't see them being convinced by this amount of evidence. Sure, I could try to argue with the reliability of the skulls we do have or the promise of future finds or the difficulty of fossilization. Those science-y arguments don't work well for the non-science-y people I'm thinking of. Human evolution asks them to overturn much of their worldview, and I don't think 6,000 data points are enough for them to do that.

(And I just realized that the number of currently known skulls is equal to what most of my people believe to be the age of the Earth. How crazy is that?)
